Unfortunately, this is a well-known issue.
Instead of building images on top of freshly built ones, we end up using images from dockerhub.
This makes many things really awkward or in many cases wrong.

#1407

We will definitely address this issue (see #1703), but this is not finished yet, because we don't have self-hosted arm runners (and we actually need them).

For now, I will close this issue, no not have duplicates.
